Reading Cannabis Labels in New Jersey

How to decode the information on NJ cannabis product packaging — potency, testing results, warnings, and what it all means for your purchase.

Every cannabis product sold at a licensed New Jersey dispensary must carry a standardized label with specific information required by the Cannabis Regulatory Commission (CRC). Understanding what each element on the label means helps you make informed purchasing decisions, dose accurately, and consume safely.

Required Label Information

The CRC mandates that all cannabis product labels include the following:

  • Product name and brand — The product's commercial name and the licensed manufacturer or cultivator
  • License number — The CRC-issued license number of the business that produced or packaged the product
  • Net weight or volume — The total amount of product in the package
  • THC and CBD content — Total milligrams of THC and CBD per package, and per serving for edibles
  • Batch/lot number — A unique identifier that traces the product back to its testing lab results
  • Testing laboratory — The name of the licensed lab that tested the product
  • Harvest or manufacture date — When the product was harvested (flower) or produced
  • Expiration or use-by date — When applicable
  • Ingredients list — All ingredients for manufactured products like edibles and tinctures
  • Universal symbol — The NJ cannabis warning symbol that indicates the product contains THC

Understanding Potency Numbers

Potency is the most important number on a cannabis label, but it is expressed differently depending on the product type:

Flower and Pre-Rolls

Potency is listed as a percentage of THC by weight. For example, a product labeled "22% THC" contains 22 milligrams of THC per 100 milligrams of dried flower. A typical joint contains about 0.5 to 1 gram of flower, so at 22% THC, that joint would contain roughly 110 to 220 mg of total THC — though only a fraction is absorbed when smoked.

Edibles

Potency is listed in milligrams of THC per serving and per package. New Jersey caps recreational edibles at 100 mg of THC per package. A common configuration is 10 servings of 10 mg each. For new consumers, 2.5 to 5 mg is generally considered a starting dose.

Concentrates and Vapes

Potency is listed as a percentage of THC, similar to flower but typically much higher — often ranging from 60% to 90%. Some labels also list total milligrams. Concentrates are the most potent products available and are recommended for experienced consumers only.

Tinctures

Potency is listed in milligrams per dropper (serving) and per bottle. Tinctures are popular for precise dosing because each dropper delivers a measured amount. Labels will specify the THC:CBD ratio if the product contains both cannabinoids.

THC vs. THCA

You may see both THC and THCA listed on flower labels. THCA is the raw, non-psychoactive form that converts to THC when heated (smoked or vaped). The "Total THC" number accounts for this conversion and is the more meaningful figure for understanding potency.

Terpene Profiles

Some NJ products list terpene content on the label. Terpenes are aromatic compounds that contribute to a strain's smell, flavor, and potentially its effects. Common terpenes you may see include:

  • Myrcene — Earthy, musky; the most abundant terpene in cannabis
  • Limonene — Citrus aroma; associated with uplifting effects
  • Linalool — Floral, lavender; associated with calming effects
  • Caryophyllene — Peppery, spicy; the only terpene known to interact with cannabinoid receptors
  • Pinene — Pine aroma; associated with alertness

While terpene reporting is not universally required for all product types, many NJ brands voluntarily include this information as consumers increasingly seek products based on their full chemical profile rather than THC percentage alone.

Warning Labels and Symbols

New Jersey requires several standardized warnings on all cannabis packaging:

  • Universal cannabis symbol — A standardized graphic indicating the product contains THC
  • "Keep out of reach of children" — Required on all products
  • Child-resistant packaging — All products must be sold in child-resistant containers
  • Government warning — Statements about the health risks of cannabis use, including impairment and pregnancy warnings
  • "For use only by adults 21 and older" — Age restriction notice on recreational products

Batch Numbers and Lab Results

The batch or lot number on your label links back to the specific laboratory test results for that production run. All cannabis products in New Jersey must be tested by a licensed independent laboratory for:

  • Potency (THC, CBD, and other cannabinoid concentrations)
  • Pesticide residues
  • Heavy metals (lead, arsenic, cadmium, mercury)
  • Microbial contamination (mold, bacteria)
  • Residual solvents (for concentrates and extracts)
  • Mycotoxins

Some brands and dispensaries provide access to full Certificates of Analysis (COAs) via QR codes on packaging or their websites. If transparency matters to you, look for brands that make this information readily available. See our Lab Testing in NJ page for more detail.

Medical vs. Recreational Labels

Medical and recreational products carry similar labeling requirements, but there are some distinctions:

  • Medical products may carry additional dosing guidance
  • Medical patients have higher purchase allotments (3 ounces per 30 days vs. 1 ounce per transaction)
  • Medical products are exempt from the 6.625% sales tax
  • Packaging for medical products is identified as part of the NJ Medicinal Cannabis Program
